Yes, especially when it is civil rights litigation, e.g. facility conditions. They will do everything within their disposal to interfere with litigation. A lot of county facilities in the USA will retain private counsel, not government lawyers, for these kinds of cases, and it is enormously expensive. I can remember one case where they took a newspaper from a prisoner and he sued, and the jail took it to trial and lost and had to pay not only damages of $15K, but also their legal fees, which were somewhere around $1.5m, but also the plaintiff's counsel, which was another $900K IIRC.

The United States has one of the highest incarceration rates in the world, with approximately 541 to 614 people imprisoned per 100,000 residents as of 2022–2026. While representing only 5% of the global population, the US holds roughly 20% of the world's prisoners, totalling over 1.8 million people.

For many crimes, the U.S. loves giving eye watering long sentences for offences that would result in a tenth of the prison time in other countries.

I read ‘helping the litigation’ to mean they both may have been involved in the same crime, and they mean to stop collusion after the fact, before trial concludes?

It's prison for a reason?
